Question

游戏开始以正确的速度运行。但是，当我按下逃生并返回主菜单，然后返回游戏时，游戏会产生一点滞后（当我在屏幕上游戏然后返回主菜单并开始游戏时）。当我一遍又一遍地这样做时，它会造成越来越多的滞后。

更多＆＃34;编码＆＃34;术语，当我按下菜单上的Start时，它会调用reset（），它会重置所有精灵的位置。当游戏结束时，它会在屏幕上显示游戏，然后用户按下escape以返回菜单。

menuOn = 1
Rooms = []
running = True #Flags game as on
screen = None
(x1, y1) = (0, 0)
(x2, y2) = (0, -screenHeight)
allsprites = pygame.sprite.Group()
clock = pygame.time.Clock()

def placeholder1(screen):
    Rooms = []
    Rooms.append(Room())
    global menuOn
    menuOn = 0
    pass

class Menu(object):
    def __init__(self,screen):
        self.screen = screen
        self.title = startMenu
        self.menu = genmenu(['START', lambda: placeholder1(screen)],['INFO', lambda: placeholder2(screen)], ['QUIT', lambda: quit()])
        self.clock = pygame.time.Clock()
        event = pygame.event.get()
        self.menu.create(self.screen)
